Letter of demand ahead of writ of mandamus?

[PaliPal]

I have submitted the webform. There are certain websites suggesting sending the demand letter to Department of Justice Canada (in Ontario, in my case). Which brings me to the original question, @PaliPal can you confirm which address/web-form/route you took to get your demand letter noticed?

Webform and I have used the same email of AbuDhabi office
